Characteristics:

Silica gel for Beer is a kind of non-crystalline micro-porous solid powder, its pore diameter

Is 8-16nm. Its chemical molecular formula is mSiO2. NH2O, insoluble in water or any other

Solvent (except the caustic alkali and hydrofluoric acid). It does not react with any acid, alkali or salt. It is nontoxic, tasteless, flame-resisting and non-explosive. It possesses high

Stability under hot or cold atmosphere and is harmless to human body, mainly used

In beer industry.

Use

1. It has large specific surface area and numerous fine-pored structure.

It adsorbs the proteins which cause beer turbid and removes them through filtering, just within several minutes, thus prolonging beer storage period by 180-240 days and keeping

Beer from being cold muddy.

2. It does not affect the beer foam or taste. Thanks to its superior physical and chemical properties, it does not have any adverse effect on the beer foam or taste. It generally recognized by the world beer industry.

3. It helps improve the filter promoting effect. It is chemically stable, contains no beer soluble substances, Its surface area and porous structure are both superior to diatomite. It is a kind of ideal filter promoter in aiding diatomite filter, making beer brighter and clearer.

Instructions:

HY-950 is suitable for use on brewery production lines equipped with diatomite filter. Likewise,

It can be filled into the diatomite precoating tank and feeder of the filter. The amount of filling is recommended as follows:

HY950 diatomite

1st precoating nil 500G/M2 filtering area

2ND precoatng 50 G/M2 filtering area 200-300G/M2

Main material filtering 30-100g/HL 80-100g/HL

(HL: Per hundred liters of beer)

2. Fill HY-950 in batches or continuously after fermenting and before filtering.

Filling in batches: Charges into the tank that is filled up with beer, keep adsorbing for at least 5 minutes. HY-950 silica gel can be totally removed during filtering.

Continuous filling: Continuously fills into beer at the given amount and passes through a container that can maintain it at a minimum of 3 minutes than the filter.

Filling amount is 300-500ppm.

Filling amount can be determined using "acceleration testing method". The method is also used to check the stabilization effect.

Take two bottles of beer and measure them with a turbid measuring gauge at the room temperature (the value measured are the initial turbid level), soak the specimens at below 0oC for 24 hours, then measure at standard 0oC. The ratio shall not be higher than the initial turbid level. The value is defined as the cold turbid level. Store the specimens at 40oC for 3 days, put them back to water for 24 hours, then measure with the turbid measuring gauge at standard 0oC. After that, heat them up again, repeat the procedure. During the measurement, if 3 EBC units are reached, the strengthening test ends. The number of days at 40oC multiplied by the factor 10 is then the actual number of days for fresh beer. It is considered far from enough just to do the above. What is more important is to check the air at the bottleneck of the specimens after the strengthening test. The air at the bottleneck of a half liter packing specimen shall be no more than 1 ml, otherwise, the results from the strengthening test become incomparable due to the influence of oxygen. Therefore, the bottles with high air values will have to be got rid of.

The strengthening test at 0oC -40oC is conducted to compare which is the best among the various stabilizers. It is proved through practice to be the most accurate. If the continuous fresh tests are to be performed, we then recommend that the strengthening test at 0oC -50oC be adopted in which the number of days at high temperature is to multiplied by the factor 20. "H value" measuring method that is commonly used in beer industry may also be adopted.

3. Beer silica gel may also be used together with other stabilizers.

A. Enzyme agent

Fill 1-2 grams of enzyme agent/HL into the treatment tank, add 30-50 grams of HY-950 silica gel/Hl when filtering the main material, this will not only help prolong the storage time, increase the foams, but brighten the beer and make the taste stable.

B. Tannic acid

Fill 2-3 grams of tannic acid/HL into the treatment tank, add 30-50 grams of HY-950 silica gel/Hl when filtering the main material, this will not only help conserve the treatment tank C. Vitamin C

After HL-950 silica gel is used for stabilization, add vitamin C (2-6 grams/HL) after the beer is filtered, this will prolong the beer storage time by 50-80%.

Packaging: 10kg per polyethylene compound bag.

Note:

1. Packing and size may be customized per your specific requirements.

2. When beer silica gel is used, the amount of fine diatomite can be reduced appropriately depending on the amount of beer silica gel being used, so as not to affect the filtering amount.

3. If the starting filter pressure is considered too fast and affects the output, we can specially produce for our customers the beer silica gel of fast filtering speed.
